I’m not sure what you mean but if the denominator is equal to zero, that makes the answer undefined. If the zero is at the top, the answer for that term is zero. To remember this I use zero UNDEr=UNDEfined
It is the stratified random sampling technique that was used by the school administrator.
Sampling methods are defined as how we choose members for study purposes from the population.When a person is not randomly selected which maybe it be biased somehow, the data may not be representative of the population. Stratified random sample, In this sampling, the population chosen is split first into groups ., the overall sample consists of some members from every group, and those members are chosen randomly from every group, this sampling guarantees that members from each group will be represented in the sample.

Let us say that y = vertical height and z =
hypotenuse <span>
dz/dt = 600
dy/dt = 0 since y (altitude) is constant
sin(θ) = 2/3
Calculating for the angle: θ = arcsin(2/3) = 0.729728 radians
sin(θ) = y/z
z sin(θ) = y
<span>We then differentiate the two sides with respect to time t:
dz/dt sin(θ)+ z cos(θ) dθ/dt = dy/dt
(600) (2/3) + (3) cos (0.729728) dθ/dt = 0
400 + [3 / cos (0.729728) ] dθ/dt = 0
400+ 4.0249 dθ/dt = 0
dθ/dt = -98.38 radians/hour
= -99.38/60 radians / min
= -1.66 radians / min = 2PI - 1.66 radians / min
<span>= 4.62 radians / min (ANSWER)</span></span></span>
